[0035] Embodiment 1
[0036] See also Figures 1 to 4 As shown, the door pull rope structure provided by the present application can be installed between the box 101 and the door 102 of an electrical appliance such as a dishwasher. The box 101 and the door 102 are hinged, and the door 102 can be opened automatically or manually to allow the user to place the dishes to be washed in the box 101, and then close the door 102, and the dishwasher performs the washing process. After the washing is completed, without adding a driving device, in order to enable the door 102 to automatically open a certain gap to allow the hot and humid air in the box 101 to be discharged, the present application sets a door pull rope structure between the box 101 and the door 102.
[0037] Specifically, the door pull rope structure includes an elastic pull rope 103 and a pulley 104. One end of the elastic pull rope 103 is connected to the box 101, and the other end of the elastic pull rope 103 is connected to the door 102. And the elastic pull rope 103 is wound around the pulley 104. The pulley 104 is slidably installed on the box 101 to form a sliding track, one end of the sliding track is the initial end 105, and the other end of the sliding track is the limit end 106. When the washing program of the dishwasher is finished, the box 101 and the door 102 are unlocked. Since the pulley 104 is slidably installed on the box 101, the friction force of the pulley 104 is small, and the door 102 is subjected to gravity so that the door 102 can swing relative to the box 101. Even if the force (the component of gravity) of the door 102 swinging outward is very small in the initial state, the elastic pull rope 103 can be pulled to drive the pulley 104 to move. During the process of the pulley 104 sliding from the initial end 105 to the limit end 106, the elastic force of the elastic pull rope 103 does not take effect until the pulley 104 is limited at the limit end 106. At this time, the elastic force applied by the elastic pull rope 103 to the door body 102, the supporting force of the hinge 108 on the door body 102 and the gravity of the door body 102 are in a balanced state, so that the door body 102 can hover at a preset position, and a gap is formed between the door body 102 and the box body 101.
[0038] The door pull rope structure provided in the present application can automatically open the door 102 of the dishwasher after the cleaning program of the dishwasher is completed through only a simple mechanical structure, so that a gap is formed between the door 102 and the box body 101, so that moisture inside the dishwasher can escape, thereby reducing the cost of the dishwasher and the power consumption during operation of the dishwasher.
[0039] In an optional scheme of this embodiment, a hinge assembly 107 is arranged between the box body 101 and the door body 102, and the hinge assembly 107 includes a hinge 108 and a hinge fixing member 109, and the hinge 108 can swing relative to the hinge fixing member 109; the hinge fixing member 109 is connected to the box body 101, and the pulley 104 is slidably installed on the hinge fixing member 109; the hinge 108 is connected to the door body 102, and the end of the elastic pull rope 103 is connected to the hinge 108.
[0040] In this embodiment, the hinge fixing member 109 is installed on the box body 101 so that the hinge fixing member 109 remains fixed. The hinge 108 is installed on the door body 102, and the hinge 108 can swing relative to the hinge fixing member 109, so that the door body 102 can swing relative to the box body 101 to achieve the opening and closing of the door body 102. Compared with directly installing the pulley 104 on the box body 101, installing the pulley 104 on the hinge fixing member 109 only requires the modification of the hinge fixing member 109, which is smaller in size and easier to process. Compared with directly connecting the elastic pull cord 103 to the door body 102, connecting the end of the elastic pull cord 103 to the hinge 108 only requires the modification of the hinge 108, which is smaller in size and easier to process, and can reduce the presence of the elastic pull cord 103, so that the appearance is more beautiful.
[0041] In the optional solution of this embodiment, specifically as follows Figures 2 to 4 As shown, the pulley 104 includes a rotating shaft 110 and a wheel body 111, the wheel body 111 is rotatably mounted on the rotating shaft 110, the wheel body 111 is provided with a groove, the elastic pull rope 103 is wound around the wheel body 111 and embedded in the groove, so that the elastic pull rope 103 is not easy to be separated from the wheel body 111. The door body 102 swings to pull the elastic pull rope 103 to drive the pulley 104 to move or rotate.
[0042] Specifically, during the free fall of the door body 102, the door body 102 pulls the elastic pull rope 103 to drive the pulley 104 to move along the sliding track, so that the door body 102 falls to a preset position. At this time, the angle between the door body 102 and the box body 101 is a preset angle ( Figure 1 If further force is applied to the door body 102 so that the angle between the door body 102 and the box body 101 is greater than the preset angle, the door body 102 pulls the elastic rope 103 to drive the pulley 104 to rotate, and the elastic rope 103 is stretched so that the elastic force of the elastic rope 103 can be balanced with the component force of gravity in the swing direction of the door body 102 (the component force gradually increases as the swing angle of the door body 102 increases), so that the door body 102 can hover.
[0043] More specifically, the hinge fixing member 109 is provided with a guide hole 112, one end of the guide hole 112 forms the initial end 105, and the other end of the guide hole 112 forms the limit end 106. The rotating shaft 110 passes through the guide hole 112, and the rotating shaft 110 can reciprocate relative to the guide hole 112. When the rotating shaft 110 reciprocates along the guide hole 112, it can drive the wheel body 111 to reciprocate synchronously, that is, a sliding track is formed.
[0044] In an optional solution of this embodiment, the elastic pull cord 103 includes a pull cord 113 and a door elastic member 114. A pull cord fixing member 115 is provided at one end of the pull cord 113, and the pull cord fixing member 115 is connected to the hinge 108. The other end of the pull cord 113 is connected to the door elastic member 114, and the end of the door elastic member 114 away from the pull cord 113 is connected to the preset end of the hinge fixing member 109, and the preset end is the end of the hinge fixing member 109 away from the hinge point. Preferably, the preset end is provided with a plurality of hooking positions 116, and the end of the door elastic member 114 away from the pull cord 113 is hooked at any hooking position 116.
[0045] In this embodiment, the sliding door elastic member 114 is specifically a spring, and hooks are provided at both ends of the spring. The hook at one end of the spring is connected to the hinge fixing member 109 installed on the box body 101, which does not affect the structure of the box body 101. The hook at the other end of the spring is connected to the pull rope 113, and the surface of the pull rope 113 is smooth. It is wound in the groove of the pulley 104 to make the movement of the elastic pull rope 103 smoother. The end of the pull rope 113 is provided with a pull rope fixing member 115, and the pull rope 113 can be reliably connected to the hinge 108 through the pull rope fixing member 115.
[0046] Furthermore, the end of the spring away from the pull rope 113 is connected to the end of the hinge fixing member 109 away from the hinge point, so that a longer spring has enough space to accommodate it, and the longer spring can adapt to a larger swing angle of the door body 102. A plurality of hooking positions 116 are provided at the preset end, and the spring can be hooked at any hooking position 116 according to the elasticity of the spring. By adjusting the hooking position 116, the angle between the door body 102 and the box body 101 can be adjusted when the door body 102 falls freely, and the pull rope 113 can be kept in a straightened state to prevent the pull rope 113 from being separated from the pulley 104.
[0047] Embodiment 2
[0048] The door body pull rope structure in the second embodiment is an improvement on the basis of the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.
[0049] In an optional solution of this embodiment, the door body pull rope structure further includes a return component; the return component is configured to apply a restoring force to the pulley 104 so that the pulley 104 has a tendency to move toward the initial end 105.
[0050] In this embodiment, when the door body 102 is closed, the elastic pull rope 103 is retracted. If the pulley 104 is still at the limit end 106, the elastic pull rope 103 will be loose and cannot be tightly wound around the pulley 104, which may easily cause the elastic pull rope 103 to be detached from the pulley 104. The present application provides a return assembly, which can apply a return force to the pulley 104 when the door body 102 is closed, so that the pulley 104 can move to the initial end 105.
[0051] Specifically, the return assembly may include the following two solutions:
[0052] Option 1: See Figure 2 and Figure 3 As shown, the return assembly is located on the side of the hinge fixing member 109 away from the wheel body 111. The return assembly includes a return spring 117 (return elastic member), a spring fixing member 118 and a spring fixing portion 119. The rotating shaft 110 passes through the guide hole 112 and is connected to the spring fixing member 118 by a screw 123. The spring fixing portion 119 is provided on the side of the hinge fixing member 109 close to the limiting end 106. At this time, the return spring 117 is a compression spring, and the two ends of the compression spring are respectively connected to the spring fixing member 118 and the spring fixing portion 119 to push the pulley 104 toward the initial end 105.
[0053] It should be noted that the pulley 104 can also be pulled toward the initial end 105 by using a tension spring, and it is only necessary to change the position of the spring fixing portion 119 .
[0054] Option 2: See Figure 4 As shown, the return component is located on the side of the hinge fixing member 109 away from the wheel body 111. The return component includes a first magnetic member and a second magnetic member. The first magnetic member can be specifically a magnet 120, and the hinge fixing member 109 is provided with a magnet fixing portion 121 at a position close to the initial end 105, and the magnet 120 can be installed on the magnet fixing portion 121 by a screw 123. The second magnetic member can be specifically a metal sheet 122, and the rotating shaft 110 passes through the guide hole 112 and is connected to the metal sheet 122 by a screw 123. The first magnetic member and the second magnetic member attract each other, which can drive the pulley 104 to move toward the initial end 105.
